Southern California -- this just in

A Laguna Beach couple who had a bottle of acid thrown into their living room by an unknown assailant Friday had been targeted before, and police do not believe it was a random attack, according to Laguna Beach police.

A hazardous material crew came to the scene after police were called by a female resident who reported that a man wearing a ski mask threw a rock through her living room window. Her husband went to chase him but he got away.

Police confirmed Monday that the suspect threw a bottle of butyric acid through the window, which is what made the three sick. He also spray-painted their garage door with the phrase "Stalk Someone Else."

The couple told police that they experienced a similar incident in January. An unknown suspect entered their garage and poured a chemical, which emitted a similar odor, on a stack of papers.
